There are countless options for powering gear on the go, but the new RIVER Bank from EcoFlow is looking to take portable power to a new level. A recent article on Mashable gives a solid overview of the new product, which is currently being funded via IndieGoGo.
Claiming to be the largest power supply you can legally take on a plane, the RIVER Bank's stackable system is modular, can be solar powered, and can even jump start your car up to 10 times on a single charge. Its Main Module provides power via two USB-A and two USB-C ports. Adding on the AC Module doubles your power capacity and lets you plug into its 100W AC supply, plus adding third USB-C port. The Car Module adds even more power, plus a jump start port and another USB-C port. When stacked, the modules can charge each other, giving you power where you need it most.
For photographers, this could mean a lot of extra battery charges in the field with a relatively small footprint. Each module weighs between 2.0 and 2.2 lbs, with the full stack coming in at 6.2 lbs. For comparison's sake, a Canon 5D Mark IV with a 70-200mm f/2.8L II comes in at about 5.25 lbs. When you're hiking several miles at a time, every pound counts, but distributing modules between two people makes for a light load and plenty of power for both.
The RIVER Bank will hold a charge for up to six months, so it's always at the ready. Pre-orders are expected to begin delivery in August 2018 for the Main and Car Modules, and in December 2018 for the AC Module.
The looks are nice but there are better options. For example Paul C Buff's Vagabond mini is $239, weighs only 3.5 pounds, has a USB connection and two 120V AC connections, 130 Wh. So to get the AC module and the main module costs about $350 and you get less of a battery pack and heavier battery.
Yep, Bufff Vagabond. Tough as hell. Also big on the GoalZero200
